G Herbo recorded himself hitting the high notes from Usher's famed "Superstar" challenge Tuesday night — and it elicited a cryptic jab from the R&B star himself.
Herb kicked things off by light-heartedly posting to Instagram that he could sing better than Usher on his "worst day."
Clearly, Usher wasn't amused 'cuz he responded with a 🧢 emoji, which means "You're lying." Of course, the legendary crooner has good reason to be a little irritable ... he recently paid homage to his grandmother, who died earlier in the week.
Waiting for your permission to load the Instagram Media.
Meanwhile, Herb captured himself on a separate IG vid squaring off against his "No Regrets" collaborator YK Dee in a B-Boy dance … the Chicago rapper was sipping a clear liquid -- or some liquid courage as they say -- with every pop lock and two-step.

Herb's fans, including Lil Wayne's daughter Reginae Carter, were eating up his brand of humor, commenting with laughing emojis.
Maybe Herb will take a stab at stand-up comedy in the new year.
